Appendix and Tonsils—Who Needs Them?

Years ago, researchers considered dozens of human organs were useless evolutionary leftovers. But research has shown all of these have functions. And yet many are still touted as useless vestiges of evolution.

For example, you’ll still hear the myth that your appendix and tonsils are useless. Now you can live without them, but they have important functions. Your tonsils help catch infections before they invade your body, keeping you healthy. And your appendix is a “safe house” for good bacteria that can repopulate your gut after a bout of illness.

Your body isn’t full of leftovers. It’s fearfully and wonderfully made.
